Patent CA-2243594-A1 (CA)
Inventor: HELGESEN JAMES P
IPC: G07F17/32
Filed: 1996-11-21
Abstract: L'invention concerne un appareil qui détecte la présence d'un jeton de jeu, qui comprend une structure de jeu (10) ayant au moins un emplacement prédéterminé (23a-23g) pour la réception du jeton. Dans un casino, cette structure peut prendre la forme d'une table de jeu (10). En chaque emplacement prédéterminé, prévu pour la réception d'un jeton sur la table de jeu, un capteur de proximité (144) est fixé à la table de jeu en alignement avec un emplacement prédéterminé. Un décodeur (152) est couplé électriquement à chaque capteur, déterminant ainsi la présence ou l'absence de jetons en chaque emplacement prédéterminé. Lorsque le décodeur signale la présence d'un jeton, on valide le pari ou la mise du joueur.

Title: Interference cancellation system for global positioning satellite receivers
Inventor: SILVERMAN GEORGE A
IPC: H04B7/10
Filed: 1997-02-13
Abstract: An adaptive polarization cancellation arrangement which nulls out all types of concurrent interference signals received by a Global Positioning System (GPS) receiver from antenna mainlobe and sidelobe situated sources. The orthogonally polarized components of the composite received signal are separated by the receive antenna (5) arrangement and adjusted in the polarization feed adapter network (7, 9, 15, 17) between the antenna and GPS receiver to optimally cancel components. The antenna and installation arrangement creates a polarization filter relative to interference sources which changes their apparent polarization orientation and supports adaptive discrimination based on dissimilar polarization characteristics relative to the desired signals.  The orthogonal received signal components from the GPS satellite constellation and from interference sources are combined to adaptively create cross-polarization nulls that adequately attenuate interference sources while slightly modifying the GPS received signals. The present network can also improve GPS signal levels and signal to noise ratio by polarization optimization or matching in non-interference environments.

Title: Process for making thermally stable metal coated polymeric monofilament or yarn
Inventor: CAWSTON JOHN D
IPC: C23C18/28
Filed: 1997-05-30
Abstract: Monofilaments of a yarn to be coated with electroless nickel are pretreated with an acid and a surfactant to render the monofilament surfaces water wettable and not substantially mechanically degraded. The pretreated yarns is passed through an electroless nickel coating bath under little or no tension so that the electroless nickel can coat all of the monofilament surfaces substantially uniformly. The nickel coated yam then can be coated with electrolytic metal such as copper in an electrolytic metal plating step, as desired.

Patent CA-2270733-A1 (CA)
Title: Optical attenuator
Inventor: CHENG YIHAO
IPC: G02B6/32
Filed: 1999-04-29
Abstract: A polarization beam sputter combiner uses a birefringent crystal that is a fraction of the size of conventional crystals used in similar devices. Since the crystal is considerably shorter in length, the beam passing through the crystal can be uncollimated, spreading very little from one end to the other. Launching uncollimated beams through a short small crystal obviates the requirement for lenses at the end face of the crystal having two waveguides coupled thereto. Since lenses are not required the waveguides at the input/output end face can be very closely spaced apart. Conventional lensed devices utilizing a pair of lenses at an input/output end face must be considerably larger in order to accommodate the lenses and resulting collimated beams.

Filed: 1997-12-16
Abstract: A method and apparatus for providing support for voice communications and data communications at a base station which has a plurality of transceivers, each having a voice mode of operation and a data mode of operation, is disclosed. A  first voice call is assigned to a first transceiver, wherein the mode of the transceiver is set to the voice mode of operation. A data transmission is assigned to a second available transceiver, wherein the mode of the transceiver is set to the data mode of operation. The data transmission is halted when a second voice call needs to be handled by the second transceiver.  The mode of operation of the second transceiver is changed from the data mode to the voice mode and the second call is initiated. The data transmission is then assigned to the next available transceiver as long as a voice call does not need to be carried, wherein the mode of the transceiver is set to the data mode of operation.

Title: Method and apparatus for total energy fuel conversion systems
Inventor: CIRRITO ANTHONY
IPC: F02K9/00
Filed: 1997-12-23
Abstract: An independent and conserved source of fuel and/or power comprises a top stage rocket engine firing up to 5000 F at very high pressures, delivering jet flows up to transonic velocities into a near adiabatic tunnel for mixing in general and/or for transforming reactants introduced to suit specific objectives. The related compression is supplied by an independent prime mover which compresses its exhaust and other recoverable fluids. Low grade flows, thereby upgraded in temperature and pressure, are adiabatically contained, are further upgraded in the tunnel to become part of the prescribed fuel for export at the tunnel ends; or fuel to be fired in a prime mover for electric or other power; or hydrogen for chemical use. Expansion turbines for this purpose are relieved of the load used to compress the excess air in standard gas turbines thus increasing export power. A portion of the expansion turbine's exhaust becomes part of recoverable fluids. When oxygen is used instead of air, the gases through turbines are nitrogen-free with more heat capacity reducing turbine inlet temperatures for the same power. When reactant transformation is specified, the larger water vapor content in the cycle enhances the water gas/shift autothermally for ammonia and/or power and alternatively for pyrolysis cracking for olefins and diolefins. Further, staging rocket engine reactors increases efficiency in boilers and steam turbines; and staging can produce sponge iron and/or iron carbide as well as expansion turbine power and fuel cells for peak and off-peak loads.
